TreeWalk calls this value "path", while "name" is the stuff after the
last slash. FileHeader should do the same thing to be consistent.
Rename getOldName to getOldPath and getNewName to getNewPath.

This is a horribly crude application, it doesn't even verify that
the object its dumping is delta encoded. Its method of getting the
delta is pretty abusive to the public PackWriter API, because right
now we don't want to expose the real internal low-level methods
actually required to do this.

The FollowFilter can be installed on a RevWalk to cause the path
to be updated through rename detection when the affected file is
found to be added to the project.
The filter works reasonably well, for example we can follow the
history of the fsck command in git-core:
$ jgit log --name-status --follow builtin/fsck.c | grep ^R
R100 builtin-fsck.c builtin/fsck.c
R099 fsck.c builtin-fsck.c
R099 fsck-objects.c fsck.c

Similar to what we did with diff, implement whitespace ignore options
for log too. This requires us to define some means of creating any
RawText object type at will inside of DiffFormatter, so we define a
new factory interface to construct RawText instances on demand.
Unfortunately we have to copy the entire block of common options.
args4j only processes the options/arguments on the one command class
and Java doesn't support multiple inheritance.

Instead of creating the DirCache from a static factory method, use
an instance method on Repository, permitting the implementation to
override the method with a completely different type of DirCache
reading and writing. This would better support a repository in the

Added a check in Diff to ensure that files that are most likely

Update a number of calling sites of RevWalk to ensure the walker's
internal ObjectReader is released after the walk is no longer used.
Because the ObjectReader is likely to hold onto a native resource
like an Inflater, we don't want to leak them outside of their
useful scope.
Where possible we also try to share ObjectReaders across several
walk pools, or between a walker and a PackWriter. This permits
the ObjectReader to actually do some caching if it felt inclined
to do so.
Not everything was updated, we'll probably need to come back and
update even more call sites, but these are some of the biggest
offenders. Test cases in particular aren't updated. My plan is to
move most storage-agnostic tests onto some purely in-memory storage
solution that doesn't do compression.

We don't actually need a Repository object here, just an ObjectReader
that can load content for us. So change the API to depend on that.
However, this breaks the asCommit and asTag legacy translation methods
on RevCommit and RevTag, so we still have to keep the Repository
inside of RevWalk for those two types. Hopefully we can drop those in
the future, and then drop the Repository off the RevWalk.

Some types of repositories might not be stored on local disk. For
these, they will most likely return null for getDirectory() as the
java.io.File type cannot describe where their storage is, its not
in the host's filesystem.
Document that getDirectory() can return null now, and update all
current non-test callers in JGit that might run into problems on
such repositories. For the most part, just act like its bare.

The new FileRepositoryBuilder class helps applications to construct
a properly configured FileRepository, with properties assumed based
upon the standard Git rules for the local filesystem.
To better support simple command line applications, environment
variable handling and repository searching was moved into this
builder class.
The change gets rid of the ever-growing FileRepository constructor
variants, and the multitude of java.io.File typed parameters,
by using simple named setter methods.

The WindowCache is an implementation detail of PackFile and how its
used by ObjectDirectory. Lets start to hide it and replace the public
API with a more generic concept, ObjectReader.
Because PackedObjectLoader is also considered a private detail of
PackFile, we have to make PackWriter temporarily dependent upon the
WindowCursor and thus FileRepository and ObjectDirectory in order to
just start the refactoring. In later changes we will clean up the
APIs more, exposing sufficient support to PackWriter without needing
the file specific implementation details.

To support other storage models other than just the local filesystem,
we split the Repository class into a nearly abstract interface and
then create a concrete subclass called FileRepository with the file
based IO implementation.
We are using an abstract class for Repository rather than the much
more generic interface, as implementers will want to inherit a large
array of utility functions, such as resolve(String). Having these in
a base class makes it easy to inherit them.
This isn't the final home for lib.FileRepository. Future changes
will rename it into storage.file.FileRepository, but to do that we
need to also move a number of other related class, which we aren't
quite ready to do.

Rather than relying on the helpers in RepositoryConfig to get

The strings are externalized into the root resource bundles.
The resource bundles are stored under the new "resources" source
folder to get proper maven build.
Strings from tests are, in general, not externalized. Only in
cases where it was necessary to make the test pass the strings
were externalized. This was typically necessary in cases where
e.getMessage() was used in assert and the exception message was
slightly changed due to reuse of the externalized strings.

Any messages received on side band #2 that aren't scraped as a
progress message into our ProgressMonitor are now forwarded to a
buffer which is later included into the OperationResult object.
Application callers can use this buffer to present the additional
messages from the remote peer after the push or fetch operation
has concluded.
The smart push connections using the native send-pack/receive-pack
protocol now request side-band-64k capability if it is available
and forward any messages received through that channel onto this
message buffer. This makes hook messages available over smart HTTP,
or even over SSH.
The SSH transport was modified to redirect the remote command's
stderr stream into the message buffer, interleaved with any data
received over side band #2. Due to buffering between these two
different channels in the SSH channel mux itself the order of any
writes between the two cannot be ensured, but it tries to stay close.
The local fork transport was also modified to redirect the local
receive-pack's stderr into the message buffer, rather than going to
the invoking JVM's System.err. This gives applications a chance
to log the local error messages, rather than needing to redirect
their JVM's stderr before startup.
To keep things simple, the application has to wait for the entire
operation to complete before it can see the messages. This may
be a downside if the user is trying to debug a remote hook that is
blocking indefinitely, the user would need to abort the connection
before they can inspect the message buffer in any sort of UI built
on top of JGit.
